Key message: Vaginal discharge is normally part of vaginal protection and changes through the cycle, pregnancy and contraception. A change from your own pattern plus smell, itching, pain or bleeding is more useful than colour alone.

Get urgent help: Seek urgent assessment for severe lower-abdominal or pelvic pain, fever, vomiting, fainting, pregnancy with pain or bleeding, heavy bleeding, or feeling very unwell. In pregnancy, watery leakage or reduced baby movements should follow the maternity pathway.

What discharge is usually normal?

  • Clear or white discharge without a strong unpleasant smell.
  • A wetter, slippery or stretchy pattern around ovulation.
  • More discharge during pregnancy, sexual activity or hormonal contraception.
  • A pattern that does not cause itching, soreness, burning or pelvic pain.

Which changes need assessment?

  • A new strong, fishy or unpleasant smell.
  • Itching, redness, soreness or swelling.
  • Pain when passing urine or during sex.
  • Yellow-green, frothy, blood-stained or clearly unusual discharge.
  • Bleeding between periods or after sex.
  • Lower-abdominal pain, fever or recurrent symptoms after treatment.

What are common possible causes?

Symptoms overlap. History alone is often not enough to diagnose the cause safely.

  • Bacterial vaginosis, often with thin discharge and a noticeable smell.
  • Thrush, commonly with itching and thick white discharge.
  • Trichomoniasis or cervicitis caused by a sexually transmitted infection.
  • Irritation from scented products, antiseptics, douching, lubricants or a foreign body.
  • Hormonal change, cervical ectropion, pregnancy or another gynaecological condition.

How is the cause diagnosed?

  • Questions about symptoms, cycle, pregnancy possibility, medicines, recent antibiotics and sexual history.
  • External and speculum examination when appropriate and agreed.
  • A vaginal or cervical swab, microscopy, pH testing or a nucleic-acid test according to the suspected cause.
  • Urine testing, pregnancy testing or pelvic assessment when pain or urinary symptoms are present.

Why is repeated self-treatment a problem?

Using antifungal medicine repeatedly can delay diagnosis of bacterial vaginosis, an STI, dermatitis or a cervical problem. Symptoms returning soon after treatment deserve testing rather than another automatic course.

Avoid vaginal douching, scented wipes, deodorants and internal cleansing; they can disrupt the normal vaginal environment and worsen irritation.

Does the partner need treatment?

It depends on the diagnosis. Some sexually transmitted infections require partner notification, testing and treatment. Routine partner treatment is not used in the same way for uncomplicated thrush or bacterial vaginosis.

Avoid sex or use condoms until the recommended treatment and testing plan is complete when an STI is possible.

What changes during pregnancy?

Normal discharge often increases in pregnancy. New smell, itching, pain, fever, bleeding or urinary symptoms still needs assessment because pregnancy changes medicine choices and the importance of infection.

A persistent watery trickle may be amniotic fluid rather than discharge. Contact the maternity unit rather than testing it at home.

What is safe self-care?

  • Wash the vulva externally with lukewarm water; use a mild unscented cleanser only if needed.
  • Keep the area dry, change out of damp clothing and choose breathable underwear.
  • Do not insert antiseptics, herbal products or homemade mixtures.
  • Complete prescribed treatment and attend follow-up when symptoms persist or an STI test is positive.

Frequently asked questions

Can discharge colour alone diagnose the cause?

No. Colour overlaps between conditions; smell, symptoms, examination and testing are often needed.

Does clear or white discharge need treatment?

Not when it is your usual pattern and there is no strong smell, itching, pain or bleeding.

Can douching prevent infection?

No. It can disrupt the vaginal environment and increase irritation or imbalance.

Should my partner always be treated?

No. Partner management depends on the confirmed diagnosis.

Can I use an over-the-counter thrush treatment in pregnancy?

Ask a clinician or pharmacist first because pregnancy affects the safe treatment choice and other causes may need testing.

Your next step

Arrange an assessment when discharge changes from your normal pattern or is accompanied by smell, itching, pain, bleeding, pregnancy or repeated symptoms. Severe pain, fever or pregnancy warning signs need urgent care.
